Nano Mania

This picture shows two gears. Many machines have gears, including cars and bicycles. But the gears in the picture aren’t found in any of the machines you’re familiar with. That’s because these gears are so tiny. They are made of individual molecules!

Why It Matters

Tiny molecular gears are an example of nanotechnology. This is technology at the level of individual atoms and molecules.

You may not be aware of it, but nanotechnology is already being used in consumer products, including clothing and sunscreens.

Nanotechnology will dramatically change the future. It has many promising real-world applications.
